Bash

Bash is the default shell on ARC’s systems. You are free to use a different shell if you’d like, however, all of our documentation only supports Bash implementations.

Check which shell you are running

Log into any research server and enter the following command:

echo $0

If you see any kind of output other than something like this:

> echo $0
-bash

then you are likely running some other shell by default, most likely tcsh or some variation of this. This command tells you what your active shell is.

What to do if my default shell is NOT bash?

Send us a quick request from your PDX email address requesting that your default research account shell be set to bash.

What to do in the meantime

You can always switch over to bash by typing the following into the console no matter what your default shell is set to after logging in:

> bash
